“Children at `Risk’ of `Brain Damaging’ Chemicals that are capable of `Impairing Child Development’ Study”

#AceHealthNews says that more and more `Children’ are being exposed to more brain-damaging chemicals than scientists thought

A troubling new study has found that the number of chemicals can impairing child development worldwide is more than double what was previously believed, according to a new story by Time Magazine.

Back in 2006, researchers from the Harvard School of Public Health and the Icahn School of Medicine at Mount Sinai pinpointed five industrial chemicals that they linked to brain disorders such as autism, attention deficit hyperactivity disorder (ADHD), reduced IQ, and more.

These chemicals were lead, methlymercury, polychlorinated biphenyls (a coolant fluid in motors), arsenic (found naturally and also in pesticides), and toluene (in paint thinner, nail polish, and more).

In a review of their 2006 study, though, the same scientists have now discovered brain development in children could be negatively disrupted by another six chemicals. These chemicals are: chlorpyrifos, dichlorodiphenyltrichloroethane, fluoride, manganese, polybrominated diphenyl ethers, tetrachloroethylene.

Alarmingly, the researchers discovered that manganese and fluoride, both of which are present in drinking water, can lead to poorer performance in school, lower math scores, and increased hyperactivity. High levels of fluoride, in particular, are potentially capable of lowering a child’s IQ by seven points.

Chlorpyrifos, meanwhile, is a common pesticide that is still used in public areas and in agriculture despite the fact that the Environmental Protection Agency banned it from residential areas in 2001.

According to a report by CNN in 2012, even low levels of chlorpyrifos could result in disrupted brain development.

“It’s out there and we do not know what the longer term impact is of lower levels,” Virginia Rauh, professor of Clinical Population and Family Health at Columbia University Mailman School of Public Health, told CNN. “But it does seem to be associated with cognitive damage and structural changes in brain.”

As RT reported this week, some health experts believe the increased rate of severe birth defects in rural Washington state could possibly be linked to prolonged exposure to pesticides, though officials have been unable to determine the precise cause.

Despite the researchers’ claim that these new chemicals can contribute to brain disorders, they admitted they could not prove a direct causal link between a chemical and any one health issue. Still, they are pushing for increased public awareness considering the potential risks.

“The consequence of such brain damage is impaired [central nervous system] function that lasts a lifetime and might result in reduced intelligence, as expressed in terms of lost IQ points, or disruption in behavior,” the study reads, cited by Time and published in the Lancet Neurology journal.

In terms of defending children from exposure, the scientists said one roadblock is the fact that regulatory agencies require a vast amount of proof in order to place restrictions on chemicals. In some cases, the EPA has even raised the level of pesticides permitted on crops grown in the United States.

“Our very great concern is that children worldwide are being exposed to unrecognized toxic chemicals that are silently eroding intelligence, disrupting behaviours, truncating future achievements and damaging societies, perhaps most seriously in developing countries,” the authors of the study wrote. “A new framework of action is needed.”

`Researchers at `UCLA’ say `Acetaminophen’ could be `Causing Children to be Born’ with `ADHD’ & `KHD’ if taken during Pregnancy’

#AceHealthNews says a `Popular Painkiller increases risk of ADHD in children, study finds, by UCLA.

PainkillersAccording to recent reports have stated that over-the-counter pain relievers made with acetaminophen are among the most widely sold in the United States, but concerns raised by a new study could possibly change all of that.

Researchers at the University of California Los Angeles say that acetaminophen — the effective ingredient in popular retail drugs including Excedrin and Tylenol — could be causing children to be born with attention-deficity/hyperactivity disorder and hyperkinetic disorder.

For years those researchers have monitored health statistics provided by the Danish National Birth Cohort to see what correlation if any exists between acetaminophen use and ADHD, as well as a particularly severe form of the disorder known as KHD.

Now after examining information pertaining to 64,322 mothers and children from pregnancy through adolescence, the study’s findings suggest there’s reason to suspect that taking acetaminophen while expecting increases the likelihood a child is later diagnosed with either disorder.

“We know there has been a rapid increase in childhood neurodevelopmental disorders, including ADHD, over the past decades, and it’s likely that the rise is not solely attributable to better diagnoses or parental awareness.

It’s likely there are environmental components as well,” Dr. Beate Ritz, one of the authors of the paper, said in a statement released this week by UCLA.

“It’s known from animal data that acetaminophen is a hormone disruptor, and abnormal hormonal exposures in pregnancy may influence fetal brain development.”

“That gave us the motivation to search for environmental causes that are avoidable,” explained Dr. Jørn Olsen, another senior author involved in the report.

Those researchers had their findings published in the latest edition of JAMA Pediatrics, and in it they warn that women who take acetaminophen for extended amounts of time while pregnant could be posing future risks for their children with regards to either disorder, characterized by the Centers for Disease Control and Prevention as causing behavioral problems like impulsivity and trouble paying attention.

According to the latest research from the team at UCLA, children whose mothers used acetaminophen during pregnancy saw anywhere from a 13 percent to 37 percent higher risk of later receiving a hospital diagnosis of HKD, being treated with ADHD medications or having ADHD-like behaviors by the time they turn 7.

“The risks for hyperkinetic disorder/ADHD in children were elevated 50 percent or more when the mothers had used the common painkiller for more than 20 weeks in pregnancy,” the researchers added.

If further research confirms the findings of the UCLA study, expectant mothers may soon be warned to avoid acetaminophen.
